Original application filed August new and useful Improvements in Car-Hauling Mechanism, of which the following is a specification.

The invention relates to an automaticcar hauling device, and more particularly to a novel device or mechanism adapted to automatically engage and propel coal cars and the like.

This application is 'a division of my copending application Ser. No. 405,699, filed August 24, 1920.

The accompanying drawings, referred to.

herein and constituting a part hereof, illustrate one embodiment of the invention, and

together with the description, serve to ex-' plain the principles of the invention.

ed asrequired for dumping, and forfeeding or propelling the empty carsalong an in-.

clined'track to bring them to grade on a Other features ofthe invention will be set forth in connection with the followingdetailed description of the illustrated embodiment. 1

Referring preliminarily to the general features of the embodiment of the invention, illustrated by Way of example in the' accom panying drawings, a novel car engaging and propelling device is provided, adapted to run upon and to be held down by a single rail, preferably of I beam form. This car propelling device is connected at each endto a cable, which is adapted todrawjthe device in either direction, that is,either backwardly or forwardly. V

The traoks'are arranged preferably. with a very slight gradient for a long train of loaded cars whereby asingle car propelling device engaging the rearfcarwill gradually progress or propel the entire train slowly forwardly the foremost car being succes .sively detached and run; forward over the.

dump, and after being dumped and being run on to an automatic switch which runs it, or them, successively back on I the. empty tracks. g

The travel of the car haul or propelling device on the empty track is preferably relatively short, and it maybe, arranged to elevate the cars one at a time up a short incline, and to return idle and rapidly after each car is so elevated. to take up the next. succeeding car, the tracks being inclined. suflicientlyto permit the empty cars to run there along and be strung together readytobe coupled into a train toreturn into the mine.

Referring now in detail to theembodiment of the invention illustrated by wayof example in the accompanying drawings, this device is adapted to run along a single rail,

and the device and rail are 'so constructed and arranged that the rail not only supports and guides thehauling devi'ce,,but the hauling device is held down in position at all times by the rail, while being free to run therealon'g. V r p H In this present illustrative embodiment, a rail 1 is provided,which maybe of ordinary I beam cross-section, and this rail may 24, 1920, Serial No. 405,699.

be laid down between the traek rails, and may be spiked or otherwise fastened to the floor or ties 2 or other support for the track rails.

' T he car hauling device comprises two plates 3 and 4, vertically disposed alongside, and extending upwardly above, the supporting and guiding rail 1. In the greater part .oftheirlength the plates 3 and 4 are spaced chains or cables, or equivalentdevice -be-fastened lntoapertures 8 1n the ends 5 apart to hold or include between them the wheels or rollers upon which the device runs and also'tohold'the car engaging device'or --dog. 'At each end the plates 3 and 4 are preferably bentinwardly witha double bend so that theyareiin contact with each'other,

as shown at 5 and 6 in Fig. 3. The hauling and-'6 of the hauling device.

As embodied, the hauling device is supportedand. progressed along the rail 1 by two rollers or wheels 9 and '10 located, respectively, neareither end of the device. These rollers are rotatably mountedon' spa-cing sleeves or" bushings 11 and 12, res-pectively, against the ends of which sleeves the plates 3 and 4 abut. and are thus properly "free to rotate as the hauling device moves along the" rail 1.

"In the embodied form of means for holding the hauling device down to the rail, there are provided near each end of the device,

' rollers 17 and 18, located on the inner side of the plates and 4, and projecting inwardlyb'eneath the top flange or tread, l? of the rail 1] The rollers 17- and 18. respec- 'tively, are mounted upon stub shafts 20 and 21'fshouldered so to hold'the "rollers jour na-led thereon, and they are alsofshouldered -to pass through apertures in the plates 3 and 4, sothat-the'rollers are held in position while being free to rotate. The shafts 20 and 21 are screwthreaded on theirexterionends to rec'eivenuts 22 and 23 to secure them in position. There are preferably a pairof these rollers at either end of the device.

The hauling device is thus free to travel along'therail '1 upon the rollers 9 and 10, while the rollers 17 and 18 prevent the device liftin' g'froin the rail while not interferinn" with its-travel along the rail. I

Referring now to the embodied form of calr'ienga'gin'g device or dog, that is, the de-' vicesupported upon the foregoing structure which engages with the 'car' to propel it car bottom.

I 'may with some part of the car 40, such as a plate 41 extendingdownwardly' from beneath the The dog has a tail 30, which acts as ,a restoring weight for the rocking dog, as later described. The car 40 asshown has the usual two pairs-of wheels 42, running on tracks 43 and 44.

The dog 28 is pivotally mounted on a spacing; sleeve 31 extending crosswise between, and having its-end abutting on, the inner sides ofthe plates 3 and 4. l he sleeve 31 is internally centrally. and longitudinally apertured and therethrough passes a bolt 32, which passes likewise through corre sponding apertures in the plates 3 and 4. The bolt 32 takes a nut 33, the bolt thus serving tohold thelplates 3 and 4 against the ends of the spacing sleeve 31, thus holding the plates together properly spaced apart,

and leaving the dog: 28 free to pivot on the sleeve 31.

As constructed, the dog 28 will rock from right to left" in Fig. "to permit a'car to ti o pass going; in the left hand direction, as

shown in the dotted line position of 2. The dog 28, however, in the full line position of Fig. 2 is rigid against any move ment to the right hand about itsp'ivot, so

that it will push any car engaged by the dog on the left hand side thereof in the left hand direction in Fig.2. Tofacilitate a car passmg the dog while traveling from right to left ill Fig. 2 the. end 29 of the dog is provided with a rear beveled face 34, against which the car may'strikel and thereby rock the dog to the dotted line position to permit the car to pass, asalready explained A su'itablestop to limit the rocking movement of the dog in this direction is provided by a bolt passing through apertures in the plates'3 and 4 and provided with "a nut 36. A similar stop with which the tail of the (log is adapted'toengage is providedat the other side by a bolt 3Tpafssing through the plates 3 and 4, and provided with a nut 38. The tail '30 is weighted or is sutliciently heavy to restore the dog" to the full line position of Fin: 2 after the cai has pa'ssed.
